PLOW.

Specification of Letters Patent.

Patented May 29, 1906.

To all whom it may concern:

Be it known that I, HYRUM S. HARKER, a citizen of the United States, residing at Murray, in the county of Salt Lake and State of Utah, have invented new and useful Improvements in Plows, of which the following is a specification.

My invention relates to plows in which by means of a shifting-lever and by the eX- change of attachments a plow may be adapted for use as a right or left hand ordinary plow, a sidehill-plow, a ditch-plow, a beetplow, and a weed-cutter. The moldboard is detachable, and the shares are removable and exchangeable. The plow is provided with a reversible point, and all its parts are quite simple in construction and readily adjusted.

The accompanying drawings illustrate the invention, its various features being referred to by letters, similar letters denoting corresponding parts in the several views.

In the drawings, Figure 1 is a side elevation of the invention with the beam partly broken off. Fig.2 is a rear elevationwith the handles broken off. Fig. 3 is a front elevation of the central portion with the beam broken off. Fig. 4 is a view similar to that in Fig. 3, but with the lever laterally adjusted and the moldboard removed; Fig. 5, a front elevation of the handles and a part of the handle-support; Fig. 6, the reversible point and bolt, enlarged; Fig. 7, the ball-and-socket brace, enlarged; Fig. 8, a view of the rod-and-lever connection.

Theletter A indicates the upright body of the plow, having the beam A, to which the horses are attached.

B is the runner, which is attached to the body by bolts 1) b.

O is a handle-support attached to and inclining rearwardly from the body A and hav ing a brace c bolted to said body.

The handles D D are preferably made in one piece, being connected at the bottom, Where they are pivotally attached to their support 0 by a bolt d.

d is an upper cross-rod, and d a lower cross-rod between the handles.

A loop E movable on the lower rod (1 has a threaded shank e, which passes through the upper part of support C and is provided with a lever-nut e by which the loop E is tightened at any point along the rod (1 By these means the handles D D maybe adjusted right or left, as desired.

F is a lever-support mounted on the upper part of the body A. It is preferably made of two parallel plates, separated sufiiciently to receive movably between them a lever f, having lateral branches f f. This lever f is pivotally secured to the support F by a bolt f. N otches f 3 f 3 are provided in the upper edge of the support to engage a spring-bolt f on said lever.

Rods G G pivotally and detachably connect the ends of lever branches f with the rear edges of removable shares H H by means of eyes g, held by nuts g.

The upper portion of the front part of the runner B inclines downward and is provided with eyes I. The shares H also have eyes it h, which with the eyes I are adapted to receive apin or bolt "L, upon which the shares move like the leaves of a hinge and from which they are easily detached and eX- changed for other shares adapted to other kinds of work. When the lever f is swung right or left, the shares H are made to tilt accordingly.

K is a double right and left moldboard detachably secured upon the shares H about the middle thereof by bolts and nuts 7c.

Besides its attachment to the shares the moldboard is supported. by a brace m, having terminal balls to engage sockets n n in the rear of the moldboard and in the front face of the body A. A head J resembling an arrow-head is formed on the front end of the bolt t, which latter has a retaining-nut t on its rear threaded end.

The head J has a flat cutting edge j, and when this edge becomes worn and dull the bolt i is partially withdrawn, and the head J is turned over and presents a sharp edge without the necessity of sharpening it.

I do not limit myself to the exact details of construction here shown; but

What I claim is 1. In a plow a runner having an inclined upper front part, eyes on said front part, a s are having eyes on its lower edge alinable alternately with the eyes on said runner, a

bolt through said eyes and a head on said bolt having cutting edges, for the purpose herein described.

2. In a reversible plow a vertical support on the rear part of the plow-body, a Vertical lever pivoted on said support, a spring-catch on said lever adapted to engage notches on said support, lateral branches on said lever and rods connecting said branches with hinged plowshares as described.

3. In a plow a double right and left moldboard detachably secured to adjustable shares and a brace having a ball at each end adapted to engage at one end a socket in the plow-body and at its other end a socket in said moldboard as described.

4. A plow provided with a laterally-rnovable lever having lateral branches and mounted on the plow-body, shares hinged by a bolt to the plow-runner, a reversible head having cutting edges on said bolt, rods pivotally connecting said lever branches with said shares, a double moldboard rernovably attached to said shares and a movable brace to support said moldboard as herein set forth.

5. A reversible plow comprising a body, a vertical support on the rear part of said body, a vertical lever pivoted on said support, a spring-catch on said lever adapted to engage notches on said support, lateral branches on said lever, rods connecting said branches with the plowshares, a runner having an inclined upper front part, eyes on said front part, said shares having eyes on their lower edges alinable alternately with the eyes on said runner, a bolt through said eyes and a head on said bolt having cutting edges as herein set forth.

In testimony whereof I have affixed my signature in presence of two subscribing witnesses.
